Wheat is a major cereal and is grown under a wide range of environmental conditions in the world. Currently, the Genetic Bank has 300 over wheat accessions. There is also missing the data of characterization and evaluation of accessions of wheat which are necessary for base collection or long-term storage. Our study is based on the characterization of the diversity of durum wheat (Triticum durum Desf.). The plant material is characterized by a survey field trial and laboratory. Analysis of variance (ANOVA) was performed to calculate the variance among the wheat accessions at a level of significance p ≤ 0.05.The purpose of this work was to study the genetic variability durum wheat lines by analyzing 15 agronomic quantitative traits. Significant differences were found among the morphological traits. The ANOVA analysis showed significant differences at p≤0.05 and the PCA revealed which of this traits. The variability found in this durum wheat could be used to select preferable traits for crosses in the improvement genetic programs. Especially the genotypes from cluster I in HCA analysis: AGB0314, AGB0317, AGB0318 and AGB0319 might have a very interesting genetic pool.
